Let's divide 91453245 by 15
We want to divide 91453245 by 15.

Going ahead to step 1:
When dividing 9 by 15, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 15

Advancing to step 2:
When dividing 91 by 15, we get 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 90 from 91 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 15

Advancing to step 3:
15 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 60.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 15

Advancing to step 4:
The number 15 fits into 145 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
Subtracting 135 from 145 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 15

Let's proceed to step 5:
103 divided by 15 is 6 with a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 6096.0
If we subtract 90 from 103, we get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 15

Advancing to step 6:
15 goes into 132 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 60968.0
Subtracting 120 from 132 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 15

Moving on to step 7:
If we divide 124 by 15, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 609688.0
If we subtract 120 from 124, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 15

Advancing to step 8:
45 divided by 15 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 6096883.0
If we take 45 away from 45, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
15 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6096883.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6096883.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6096883.0, with a leftover of 0.0.
